VIDEO: Volcano erupts on Hawaii's Big Island, produces steam cloud

Hawaii's Kilauea Volcano on the Big Island erupted and shot a steam and ash cloud into the atmosphere that lasted about an hour, an official with the National Weather Service said early Monday.

The eruption began late on Sunday within Kilauea's summit crater, the U.S. Geological Survey said. The crater, named Halemaumau, is located within Hawaii Volcanoes National Park and was home to a longstanding lava lake that was present for years before a 2018 eruption caused it to drain.

Tom Birchard, a senior forecaster with the National Weather Service in Hawaii, said lava interacted with a pool of water that had accumulated inside the crater, leading to a short-lived but fairly vigorous eruption.

When lava interacts with water it can cause explosive reactions.

All the water evaporated out of the lake and a steam cloud shot up about 30,000 feet (9 kilometers) into the atmosphere, Birchard said.

The water was the first ever recorded in the summit crater of Kilauea Volcano.

In 2019, after a week of questions about a mysterious green patch at the bottom of the Volcano’s crater, researchers confirmed the presence of water. The lake had continued to fill since then.

An advisory was issued by the National Weather Service in Honolulu, warning of fallen ash from the Volcano. Excessive exposure to ash is an eye and respiratory irritant, it said. The agency later said the eruption was easing and a "low-level steam cloud” was lingering in the area.

By 1 am, USGS officials told Hawaii News Now that there were reported lava fountains shooting about 165 feet (50 meters) into the sky.
David Phillips, a Hawaiian Volcano Observatory spokesman, said the agency was monitoring the "rapidly evolving” situation.

"We will send out further notifications on Kilauea and other Hawaiian Volcanoes as we observe changes,” he said.

A magnitude 4.4 earthquake hit about an hour after the Volcano began erupting.

The USGS said it received more than 500 reports of people who felt the earthquake but significant damage to buildings or structures was not expected.
